Quantification of the Induced Electric Field in a Material Sample Placed within an Energized Cylindrical Cavity

Mode-Matching Analysis of the Induced Electric Field in a Material Sample Placed within an Energized Cylindrical Cavity

“…4. The corresponding results generated from an integral equation method [1] are plotted in the same figure for comparison. We observe a good agreement between these two sets of numerical results generated by two different methods.…”

“…As stated before, we restrict the material samples which are placed in a cylindrical waveguide to be of simple cylindrical shapes and homogeneous. The numerical results obtained will be compared with the corresponding results derived using the integral equation method [1]. In the numerical computation, the eigenmodes in region II are derived first after the dimensions and the dielectric parameters of the material sample are selected.…”

“…In a companion paper [1] published in this issue, an electric field integral equation (EFIE) method was developed to quantify the induced electric field inside a material sample placed in an energized cavity. It was demonstrated that the integral equation method is a powerful technique because it can handle the material sample of arbitrary shapes and heterogeneities.…”

Microwave ovens electromagnetic field analysis by means of boundary element method

“…Several authors have approached the electromagnetic field computation in dielectric-loaded cavities (e.g., [1] and references there). Although the theory behind the process is well established, the setup of some efficient numerical procedure for the field computation is far from being a trivial task.…”

“…The electromagnetic field generated by magnetrons is applied through waveguides to the ovens cavity where it will interact with the material of the sample. A good measure for this process is the microwave energy absorption rate [1]. To this end an accurate distribution of the induced electric field at any point in the material sample is needed.…”
